Force download of all projects with lightweight permission download

Question

I am using Visual Studio 2017 and lightweight solution download. This is a great performance improvement, especially when I just switch between different branches.

However, sometimes I want to load every project inside my solution. Currently, I right-click my solution in the solution explorer and open the configuration manager, which does what I want (but the configuration manager shows).

Is there a better way to achieve this, preferably in the background, so I can continue to print, and visual studio loads all the projects in the background.
